-
Elevator is at rest: the scale will read normal weight of the object,
W = mg , wherem is mass andg is acceleration due to gravity. -
When the elevator is rising with an acceleration
a=g :
Scale will show that weightW=m(g + g) = 2mg . - When the elevator is moving down with an acceleration
a=-g :
Scale will show that weightW=m(g - g) = 0 .
